音响设备的音质功能肯定比其他音响的好，音响设备在使用的时候需要注意哪些事项呢？
The sound quality function of professional audio equipment is certainly better than that of other audio equipment. What should be paid attention to when using professional audio equipment?
1、如果音响设备长时间工作在较大的输入功率的状态下，音圈可能由于温度达到一百度以上而导致音箱烧毁。因此需要有一个能保证扬声器长时间正常工作的输入电功率，即额定输入功率，这个数据在设备的资料里都会给出，重要的是在使用中要严格执行，在扩声效果不如人意的情况下应考虑改变配置，而不是简单地加大功率。
1. If the professional audio equipment works for a long time under the condition of large input power, the voice coil may burn out because the temperature reaches more than 100 degrees. Therefore, it is necessary to have an input power that can ensure the normal operation of the speaker for a long time, that is, the rated input power. This data will be given in the data of the equipment. It is important to strictly implement it in use. When the sound reinforcement effect is not satisfactory, we should first consider changing the configuration rather than simply increasing the power.
2、音响设备如果使用不适当很容易引起啸叫，为了减小散射声，提高清晰度，要尽量把音箱的作用区指向受众的座位方向。
2. If professional audio equipment is not used properly, it is easy to cause howling. In order to reduce the scattered sound and improve the definition, try to point the action area of the speaker to the audience's seat.
3、工作中经常同时使用多个音箱，在连接它们时一定要注意极性问题，所有的扬声器应当极性一致，如果连接后的扬声器极性不同，则声音输出将相互干涉，听起来感觉低音不足，明显的不调和音。
3. Multiple speakers are often used at the same time. When connecting them, pay attention to the polarity. All speakers should have the same polarity. If the connected speakers have different polarities, the sound output will interfere with each other. It sounds like the bass is insufficient and there is an obvious disharmony.
4、放大器与音响设备之间的功率要匹配。重放声音的综合音质不仅取决于音箱的特性，也取决于放大器的输出及负载特性。如果声音不理想，不要只想到是音箱出了问题，而应当考虑与它相连的放大系统是否存在问题。
4. The power between the amplifier and professional audio equipment shall be matched. The comprehensive sound quality of playback sound depends not only on the characteristics of the speaker, but also on the output and load characteristics of the amplifier. If the sound is not ideal, don't just think that there is a problem with the speaker, but first consider whether there is a problem with the amplification system connected to it.
